Installation depth is 70 mm. It's not a residential-grade device. Sealable terminals let you lock out adjustment after commissioning — useful for machines that must meet lockout/tagout procedures. Rated for 10 000 mechanical operating cycles — that's the life of the mechanism, not the electrical endurance under fault. For a panel that sees frequent switching (like a machine tool with daily power-down), that's a solid service life. Listed to IEC / EN 60947-2 and UL 1077 / CSA C22.2 No.235. The UL 1077 listing is supplemental protection — not a branch-circuit rated breaker under UL 489, so verify your local code's requirement before specifying it as the sole overcurrent device on a feeder. Vibration resistance tested to IEC 60068-2-6: ±1 mm at 5 to 25 Hz, 50 m/s² at 25 to 150 Hz. That covers most industrial machinery vibration profiles — pumps, compressors, conveyors. Temperature influence data shows derating above 55 °C: max 95% humidity at 55 °C, dropping to 55% at 70 °C and 35% at 75 °C.","metaTitle":"Siemens 5SY8325-7 SENTRON MCB, 3P C-Char, 30kA IEC","metaDescription":"Siemens 5SY8325-7 SENTRON miniature circuit breaker, 3-pole, C characteristic, 30 kA IEC 60947-2, 400 V AC, UL 1077 listed.

The physical fit is identical — same 3-module width, same terminal layout — but the trip curve difference means you must verify the load's inrush profile. For resistive or lightly inductive loads the swap is clean; for motor circuits the C curve is actually the better choice."},{"question":"What compliance documentation does this brand provide for 5SY8325-7?","answer":"The breaker carries IEC/EN 60947-2 and UL 1077 / CSA C22.2 No.235 certifications.
